He whānuitia te whakamahinga o ngā karāhe PC (ngā karāhe polycarbonate) i roto i te umanga mōhiti kanohi nā ō rātou painga pēnei i te māmā me te ātete kaha ki te pānga. Heoi, he iti te pakeke o te mata, ā, he ngāwari te rakuraku, nō reira me whakapakeke kia pai ake ai te ātete ki te kakahu. Anei tētahi tātaritanga taipitopito o te tukanga whakapakeketanga o te karāhe PC:

1. Te kaupapa matua o te tukanga whakapakeke

Te maimoatanga turanga: Horoia te mata o te arotahi mā te whakamahi i ngā tikanga matū, ā-tinana rānei hei tango i te hinu me ngā poke, hei whakapakari ake hoki i te piri o te paparanga kua whakapakeketia.

Paninga mārō: Pania te mata o te arotahi ki tētahi rauemi mārō (pērā i te kapia silicone) ka hanga he paparanga ātete-kakahu mā te whakamaroke.

Hangarau whakaora: Ko te whakaora UV, ko te whakaora wera rānei te mea e whakamahia whānuitia ana hei hono pūmau i te paninga ki te papa PC.

2. Ngā tikanga whakapakeke matua

(1) Paninga tōpana

Tukanga: Rukuhia te karaihe ki roto i te wai whakapakeke → Tōia ki te tere pumau hei whakahaere i te matotoru → Whakamaroke UV/wera.

Ngā Painga: He ōrite te paninga, ā, he pai mō te hanga papatipu.

Ngā kōrero matua: Te tauira wai whakapakeke (tae atu ki te nano-silica me ētahi atu kai) me ngā āhuatanga whakapakeke (te kaha o te UV, te pāmahana).

(2) Paninga Hurihuri
Tukanga: Ka whakauhia te arotahi ki runga i tētahi tēpu hurihuri, ka tāpirihia he wai mārō → te hurihuri tere-rahi, kātahi ka whakaranua kia ōrite → te whakapakeketanga.
Ngā Painga: Matotoru ka taea te whakahaere, he pai mō ngā whakaritenga tino tika.
Ngā Huakore: He nui te para o ngā rauemi.
(3) Paninga Korehau
Hangarau: Ka whakatakotoria ngā kiriata mārō kore-waro pērā i te SiO₂ ki te mata mā te PVD (whakatakotoranga kohu ā-tinana).
Ngā Āhuatanga: Tino mārō (tata ki te karāhe), engari he nui te utu me ngā taputapu motuhake e hiahiatia ana.
(4) Maimoatanga Plasma
Mahi: Ka horoi i te mata, ka whakahohe i ngā ngota i roto i te plasma hei whakapai ake i te piri o te paninga.
Te Whakamahinga: He maha ngā wā e whakamahia ana hei maimoatanga i mua i te whakatō, hei whakamahi tahi rānei me te tikanga tō.
3. Ngā Rauemi mō te Paninga Mārō
Te kapia hiraka: te kōwhiringa matua, te hanga i tētahi whatunga honohono mā te whakamaroke UV.
Ngā rauemi nanocomposite: pērā i te nano-SiO₂ me te Al₂O₃ kua marara ki roto i te kapia, ka tino whakapai ake i te pakeketanga.
Polyurethane acrylate: he ngāwari pai, he ātete kaha ki ngā pānga.
4. Ngā Tawhā Tukanga Matua
Ngā Āhuatanga Whakamaroke: Ngā roangaru UV (te nuinga o te wā 365nm), te pūngao (500-1000mJ/cm²), te pāmahana (60-80°C).

Matotoru o te Paninga: Ko te tikanga 2-5μm. Ka ngawari te pakaru o ngā paninga matotoru, engari ko ngā paninga angiangi kāore e ātete ki te pakū.

Whakahaere Taiao: Rūma kore puehu (ISO Class 7, teitei ake rānei), haumākū 40-60%.

5. Ngā Paerewa Tirotiro Kounga
Ātete ki te Waro: Whakamātautau Waro Taber (wira huri CS-10, kawenga 500g, huringa kohu ≤5% i muri i te 1000 huringa).

Piripiri: Whakamātautau Maripi Mata (ASTM D3359, 4B, teitei ake rānei).

Pakeke: Whakamātautau Pakeke Pene (≥3H e whakaaetia ana).

Ātete ki te Huarere: Whakamātautau Pakeketanga UV (kāore e ngatata, kāore hoki e kōwhai i muri i te 500 hāora).

6. Ngā Raru me ngā Otinga Noa
Te Whakakore i te Paninga: Whakapai ake i te maimoatanga mata (pēnei i te whakahohenga plasma) te whakarerekē rānei i ngā tawhā whakamaroke.

Kiri karaka mata: Nā te matotoru rawa o te otinga whakapakeke, te tere hurihuri koretake rānei o te paninga; me whakarerekē te hanganga, te tukanga rānei.

Mirumiru: Te tango hau mā te korehau, te whakaiti rānei i te tere tō/hurihuri.

7. Ngā Auahatanga o te Ahumahi
Ngā paninga nanocomposite: Ka whakamahia ngā rauemi nano (pēnei i te graphene) hei whakarei ake i te pakeketanga me te pupuri tonu i te tuku mārama.

Ngā tukanga hoa taiao: Ka whakakapia ngā otinga whakapūmau wai ki ngā otinga whakapakeke, ka whakaiti i ngā tukunga VOC.

Ngā paninga maha-mahi: Whakauruhia ngā āhuatanga tiaki mārama kikorangi, ārai-kohu, me te ārai-pūmau.
